UNITED STATES AMEDEE FONTAINE, OF MILWAUKEE, WISCONSIN.

IMPROVED FIRE-ALARM.

Specification forming part of Letters Patent No. 59,379, dated November 6, 1866.

To all whom it may concern:

Be it known that I, AMEDEE FONTAINE, of Milwaukee and State of Wisconsin, have invented a new and Improved Mode in Fire- Alarms; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same,

'. lever-bar, spiral sprin guide-rod for spiral spring, bell-wire, and position of expansionwire when the alarm is set ready for use; Fig. 4, letter D, shows the position of the detachin g-lever, (in dotted lines,) lever-bar, operatinglever, and spiral spring after having been used Fig. 5, letter E, sectional View.

In any convenient part of a room or buildin g, and suitably attached to the wall or woodwork thereof, maybe affixed the plate or slab holding the several parts or pieces of my firealarm, which, as will be seen by referring to the several figures of the drawings, is made up of a detaching-lever, f, an operating-lever, g,

i a lever-bar, h, a coiled spring, t, a guide-rod, j,

for the spring, a fulcrum-pin, k, for the detaching-lever, an expansion rod or wire, I, and a bell-wire, m.

The lever h is connected to a bar, a, which is a part of the frame of the alarm, and has limited motion both at the end connected to the bar a and the other end attached to the lever g.

The lever g is pivoted to a head, 0, that traverses the guide-rod j, and the relation of these parts to each other and to the spring is such that when the lever g is forced back, as shown by Fig. 3, the spring will be compressed,

and the lever y will hold the head 0 against the end of the spring. When these parts are thus placed, the detaching-lever, which is pivoted at 70, will lie horizontal, or nearly so, with its weighted or heavy end lightly resting on the end of the lever g, the expansion copper wire lholding it in this position, and the alarm is then set. This position is indicated by Figs. 1 and 3.

In case of fire the expansion rod or wire, becoming heated, will yield to the weighted end of the detachinglever f, by which the lever y will be forced from its set position, allowingthe springt' to act, and with its extension carry back the head 0, and the bell-wire m, attached to it, so that an alarm will be given. This second or unset condition of the parts is indi- Oated by Figs. 2 and 4..

One or more of these alarms may be used in a building or room, and the expansion rod or wire may pass through several rooms, bellcranks or other suitable. means being used to complete the arrangement. At certain points, in case the wires of several rooms are connected, the expansion-Wire should be firmly fixed, so as to answer the same purpose as the wire of the one room'i. 6., while one end of the expansion-wire is connected to the detach ing-lever f, the other end should in some way be rigidly held.

What Iclaim as my invention, and desire to secure by Letters Patent, is-

The detaching-lever f, the operating-lever g, the lever-bar 'h, the spiral spring i, the expansion-wire l, the bell-wire m, in combination, substantially as described, and for the purpose set forth. I
